“Diamond Bar prepared me in many ways but I believe he helped me most by teaching me to become a better man. It wasn’t just focusing on the workouts, he taught us life lessons everyday. Diamond Bar prepared us that one day football isn't going to be there for us and you’re going to have to find something else to make you happy.

He was a major factor on how fast I recovered from my ACL and MCL surgery during my senior year of high school. I rehabbed with him almost every day to be able to be on the field at full speed 6 months after surgery. He also vastly improved my technique on all of my lifts. Before Coach, I used to do them how I thought they were suppose to be done and usually ended up getting injured and therefore sat out lengthy periods of time. Now I'm usually teaching people at my college on how to do the lifts correctly. He taught me how to train smart and how rest is just as important as the workouts.

My body control improved the most from my hips to my hand eye coordination. I am able to control my body more fluently, by being able to break out of cuts cleanly to jump at full speed and locate the ball in the air. I also improved greatly in my explosion. By focusing on big lifts, using multiple muscles, we noticed a huge increase in our muscle growth.” – Brandon S. (Student-Athlete, Citrus College)

“All of the lifts I did in high school translated into college. During high school, I learned how to perform a variety of different lifts with great technique and form. Most of these lifts were Olympic style lifts and learning them in great detail in high school really gave me an advantage when I entered USC’s football program. A lot of the lifts, such as front squat and rear foot elevated split squat, I believe really helped me with my speed and power. My 40 time, pro agility, and vertical all improved dramatically after I began training with Coach and his program. I felt my body getting stronger and I was able to compete at a higher level.” – George K. (Student-Athlete, University of Southern California)

“Diamond Bar's high school strength and conditioning program has prepared me for the next level in a huge way. “Attention to detail” this is Coach’s favorite quote and is basically what his whole philosophy is based off of. Coach never throws kids into things unprepared, he makes sure that they are properly stretched, warmed up and then makes sure that they have perfect form on everything. He prides himself in form for everything that he teaches and established that same pride of form into me. As a kicker probably the two most important things for me are attention to detail and my form and that is exactly what Coach taught me over the years. Coach still to this day coaches me up and checks in on me and it is very evident that none of his philosophies have changed at all.

Some specific skills that I feel I have improved on are my power and speed. Going into my senior year I gained 25 lbs. of muscle from Coach’s workouts and also his nutrition advice that he constantly shared with us on a daily basis. All my maxes were at the highest they had ever been before and by a huge margin. My speed was a very surprising improvement especially since I am only a kicker. Before my senior year testing I had never gotten a 4 second 40. On my 40 my senior year, I ran a 4.82 and was very impressed by the improvements that I had shown under Coach. My power has increasingly gotten better through Coach Lim’s strength program; he always wanted us to focus on speed while still maintaining perfect form of course. The power that I have developed through Diamond Bar’s coaching has shown in my kicking and the extra distance that was the result in the workouts.

In my personal opinion I have never been around a coach that wants each and every player and student for that matter to be so successful. This success is not just for sports but is for academics and life. One of his main preaching points is making goals and working towards them. Now many people say this often but I have seen kids effected by these words and have changed their lives because of it. I am one of them.” – Brian D., (Student-Athlete, Northern Arizona University)
